Interfacial thermal resistance

（重定向自Kapitza resistance）

Typical Interfacial Resistance of Liquid Helium with metals. Resistance has been multiplied by T3 to remove the expected T−3 dependence. Adapted from [6]

Thermal Conductance Data adapted from,[9][10][11]

Interfacial thermal resistance, also known as thermal boundary resistance, or Kapitza resistance, is a measure of an interface's resistance to thermal flow. This thermal resistance differs from contact resistance (not to be confused with electrical contact resistance), as it exists even at atomically perfect interfaces. Due to the differences in electronic and vibrational properties in different materials, when an energy carrier (phonon or electron, depending on the material) attempts to traverse the interface, it will scatter at the interface. The probability of transmission after scattering will depend on the available energy states on side 1 and side 2 of the interface.
